Application filed April 5, 1888. Serial No. 269,715. (No model.)

To a/ZZ whom t 711,603/ cm1/cern,-

Be it known that we, LOUIS DUCROS and EUGENE TYMESON, both of Yonkers, in the county of XVestehester and State of New York, have made an invention of certain-new and useful Improvements in Dyeing Apparatus; and we do hereby declare that the following, in connection with the accompanying drawings, is a full, clear, and exact description and specification of the same.

Previous to our invention it has been Icustomary to hang the hanks of yarn which are to be dyed upon poles and to lower them into the dye-vat until the poles rest upon the opposite edges of the vat, and after the portions of the hanks of yarn which are hanging in the dye-liquor become wet-ted by it it has been customary to shift the banks upon the poles by hand, so that the portions of said hanks which have been wet with thedye-liquor are drawn from the dye-vat, and the portions which rested upon t-he poles are let down into the dye-liquor. In order" that the yarn may be dyed equally, this shifting of the hanks has to be repeated a number of times, and consequently a large amount of labor has been heretofore required for this purpose. In addition to this, various machines have been devised to shift the hanks or skeins of yarn in the dye-liquor, and ,so far as we know these machines operate upon the following plans: In some of them the skeins of yarn arehung upon rollers or upon reels, which are revolved so as to cause the skeins to move Y like endless belts running on pulleys. In others the skeins of yarn are held on revolving creels or frames which revolve in the dyeliquor. In others again the skeins are pulled laterally over the poles, but without raising the yarn from the poles. A machine also has been devised to lift and lower poles carrying hanks of yarn by means of two sets of hooks7 one set of which is stationary during the transfer of the poles, while the other set of hooks has a compound movementimparted to it; but this machine necessitates the employment of two poles for each row of hanks and an intermediate transposition of the two poles.

The object of our invention is to operate upon the hanks or skeins or similar articles while in the dye-liquor by machinery in a manner similar to the manipulation of the skeins or hanks by hand, so as to attain the good effects in the dyeing of yarn which are incident to the hand manipulation of the skeins or hanks and at the same time reduce greatly the labor required.

Our invention consists of certain combinations of mechanical devices by means of which the hanks of yarn or other similar articleshanging upon poles may be shifted in the dye-liquor without hand labor. These combinations are set forth in detail in the claims at the close of this specification; and when our entire invent-ion is used the hanks of yarn hanging upon any one pole are not lonly shifted lin the dye-liquor, but each pole of a series upon which hanks of yarn are hung 1n a dye-vat has the hanks upon it shifted in succession, so that all the hanks of" yarn which are being dyed at any one timeA in the same dye-vat are shifted in the dyeliquor the requisite number of times required to complete the dyeing of the yarn.

In order that our invention may be fully understood, We have represented in the accompanying drawings and will proceed to describe the form of dyeing apparatus which we prefer to use, and which embodies all parts of our invention in the best form at present known to us.

Figure l of said drawings represents a plan of the said apparatus with certain portions removed between the broken lines at a; 5c of the said figure. Figs. 2, 3, and Lt represent conjointly a side view, upon a larger scale than Fig. l, of the said apparatus, each figure representing a section of about one-third of the total length. Fig. rrepresents a view of that end of the apparatus at which the camshaft of the lifting apparatus is located. Fig. 6 represents a partial transverse section of the apparatus at the line ir of Fig. et and on the same scale as Figs. 2, 3, and 4. Fig. 6 represents a longitudinal section of the inner ends ofthe shifting-rods. Fig. 7 represents a top view of one of the shifting-rods and its connections. Fig. 8 represents an elevation of the same with the rraising arm and lever in section at the lines a; .fr of Fig. 7. Fig.-9 represents a side view of the inner side of the end of one of the raising-arms and its appurtenances, and Fig. l0 represents a longitudinal section of the same. Fig. ll represents a side view of the lifting-cam and its appurtenances. Fig. l2 represents a side view of one of the shifting-rod cams and some of the connectionswith the shifting-rod. Fig. 13 represents a side view of apart of the apparatus, showing an automatic stop mechanism, which we prefer to use, as hereinafter described.

The dye-vat A of the said apparatus is of rectangular form,v and is .preferably deep enough to permit the banks of yarn to hang in it from poles without touching the bottom. Its width should be adapted tothe number of banks of yarn which are to be placed upon the poles, a convenient width being about three and one-half feet. The length of this dye-vat should be adapted to the number of poles which are to be used for holding the banks of yarn, and when the machinery is constructed in the form represented in the drawings we prefer that the distance between two successive poles should be about seven inches. The dye-vat sets within a frame B, which sustains the various moving` parts of the apparatus. The series of poles C, from which the `banks of yarn are suspended, extend transversely across the dye-vat, and when the apparatus is in use these poles are sustained by a pole-carriage D, which is preferably made movable lengthwise of the main frame by being iitted with wheels d, that run upon longitudinal rails b, which are connected with the main frame B, so vthat tbe pole-carriage with the poles C and the banks of yarn hanging thereon may be moved to and fro longitudinally of the vat for the purpose of placing each pole in succession in the proper position to have the banks of yarn upon it shifted,

'In order that the poles with the banks .of yarn may be readily applied to and removed from the dye-vat, we prefer to connect the poles with a movable frame D', which may be raised bodily from the dye-vat, and may be replaced by another pole-frame of the same character having a new set of banks applied to its poles. The ends cof the poles are preferably notched at their under sides to rest upon the sides of the pole-frame, and those sides d2 also are preferably notched at the requisite distances to hold the poles in their proper relative position. Each pole is constructed in such manner as to permit it to betraversed longitudinally by a shiftingrod, and the construction of pole whih we prefer for this purpose is a pole of gutter form or U section, (as represented in the drawings,) open at the top, so that the shiftingrod, after being inserted endwise into the cavity of the pole and into the bights of the banks of yarn hanging upon the pole, maybe raised, so as to lift the banks of yarn from the pole. If the dye-vat be sufficiently narrow, a single shifting-rod maybe used to raise the hanks of yarn from the pole; but we prefer to use two shifting-rods E E, which. are arranged at opposite sides of the pole-carriage, are inserted endwise into the 1nights of the banks of yarn, are then raised to lift the said banks, and are subsequently lowered to lower the said banks into'the dye-liquor, after which the shifting-rod is withdrawn endwise from the said banks.

The mechanism which we prefer to use to impart these reciprocating 'movements to the shifting-rods is as follows: Each shiftingrod E is supported by an arm F, by means of which it may be raised and lowered, and

is connected with a lever G, by means of which it may be inserted endwise'into and withdrawn fronl'the banks of yarn.. As two shifting-rods are used in the mechanism represented in the drawings, the two lifting-arms F F of the two shifting-rods E E are secured to a common rock-shaft G', which is fitted with an intermediate arm F', and this int-ermediate arm is operated by the lifting-cam F2 through the intervention of a lever f and alink f', so that as the said lifting-cam F2 revolves the shiftingrods that are carried by said arms are raised and lowered or reciprocatedvup and down relatively to the pole-carriage. The lifting-cam F2 is secured to a cam-shaft H, which is fitted to turn in suitable bearings upon the main frame B, and has a revolving motion imparted to it through the intervention of the cog-wheels and pinions a a a2 and shafts a* c5 by means of a belt applied to the driving-pulley I. The lever G, by means of which the shifting-rod is inserted and withdrawn endwise from the banks of yarn, is pivoted to an extension g of the rock-shaft G of the raising-arms. The longer arm of this lever is connected pivotally with the outer end of the shifting-rod E, and the lever is vibrated in horizontal directions lfor the purpose of inserting and -withdrawing the shifting-rod by means of a cam E,which we call the shifting-cam, and which is secured to the cam-shaft H and operates uponthe said lever G and the shifting-rod E through the intervention of the lever g', which swings on the fulcrum-stud g5, Fig. 2, the rod g2, the elbow-lever g3, and a connecting-rod g4. The reciprocation of the shifting-rod in a direction endwise of its length, for the purpose of entering into and withdrawing from the skeins or banks of yarn hanging on the poles, is an essential feature of the invention, and whenever hereinafter the cndwise-1eciprocating shifting-rod is mentioned it is to be understood as one having that endwise-reciprocating movement.

Each endwise-reciprocating shifting-rod is fitted to slide endwise in the end of the lifting-arm F, and as the two reciprocating shifting-rods are inserted from opposite sides of tbc dye-vat, so that their inner ends come together, they are capable of lifting all the IOO IIO

ted with a spring hanks of yarn upon the pole in connection with which they are operating. lrVhen two endwise-reciprocating shifting-rods are so used, we prefer that the end of one of the two should be fitted with a pin or dowel f2, Fig. G, and that the innerend of the other shifting-rod should be socketed to receive the dowel, and that the endwise motion imparted to the shifting-rods by their cams E should be sufficient to cause the dowel f2 of one rod to enter the socket of the other rod, so that the inner ends of the two shifting1ods are then connected, because such connection tends to render them stiffer when raising the hanks.

rlhe shifting-rods may be constructediwith advantage of drawn-copper tubes, as this' material is light and sti 'When an endwise-reciprocating shifting` rod is withdrawn from the hanks, it is-desirable that the hanks should be preventedfrom moving along with the shifting-rod. Inorder to prevent such movement, the'lifting-arm of a shifting-rod is fitted with a stripper eLwhich is preferably arranged to slide in a guide j, Figs. 7, S, 9, and l0, at the outer end of said arm above the shifting-rod E. The stripper is fitwhich tends to hold it in its outermost position, as represented at Fig. 8, and a shoulder e is connected with the outer end of the shifting-rod E to operatel upon the outer end of the stripper J' and plush that stripper inward as the shifting-rod reaches its innermost position, so as to push the hanks of yarn toward the inside of the dye-vat.

1n order that each pole C of the series on the pole-carriage D may be carriedlongitudi .nally of the dyevat, the pole-carriage D is moved or fed longitudinally of the said vat, and the moving' or feed mechanism which we prefer to use for this purpose is as follows: A rack-bar K is secured to thefcarriage, and a reciprocating feed-pawl K is provided to engage with the teeth of the'said racknbar and move it and the pole-carriage forward. The said feedpawl is pivoted to the upper end of a pawl-lever It, which is operated by the feed-cam K2 through the intervention of a lever It', which swings on' the fulcru 11i-stud kw, Fig. 2, rod 71:2, counter-lever 7c3, and rod 7a4. The feed-pawl K is preferably moved in a forward direction only bzy the action of the feed-cam K2, and in this ycase the return move ment of the feed-pawl is effected by means of a spring L5.

In order that the pole-carriage D may not bc retrograded during the backward movement of the feed-pawl, a Stop-pawl k6 is provided to drop in behind the teeth of the rackbar in succession and prevent such retrograde movement.,5

In the operation of the said machine it is expedient that the bights of the hanks of yarn after being raised from the pole should be lowered, so as to drop into t-he vat between the pole from.; which they were raised and the next succeeding pole, so that portions of the hanks which previously to the raising hung ered. Hence the lengths of the teeth of the rack-bar K are preferably equal to half the distance between two successive poles yC C,

and the reciprocating movement imparted to the feed-pawl K is sufficient. to move the polecarriage the said half-distance. X/Vhen the carriage has been fed or moved forward sufiiciently to present the series of poles in succession to the reciprocating shifting-rods, the feed mechanism is disengaged or temporarily stopped by raising the feed-pawl and stoppawl, and the carriage is then retrograded. This retrograde movement of the carriage may beeffected by means of a feed mechanism operating in the reverse direction to that above described; but we prefer to effect it by means of a weight K4, connected by a rope k7 with one end of the carriage. In order that the carriage may be stopped when it has been retrograded by the weight K4, a bumper L is provided in position to be struck bythe rear end of the carriage when it reaches its rearmost position, and we prefer that the face of d this bumper shall be a spring-such, for example, as a block of indiarubberto prevent excessive jar. l

In order to facilitate the operation of the apparatus, we have combined the pole-carriage with means for disengaging the feedpawl and the stop-pawl from the feed-rack when the pole-carriage reaches the end of its forward movement and for permitting the reengagement of the said two pawls with the feed-rack when the pole-carriage reaches the end of its retrograde movement. For this purpose a slide N is provided, and is fitted with two pins n, Fig. 13, which are arranged to move in inclined slots n n, formed in a plate N', secured to the frame B of the machine, so that when the said slide is movedin a forward direction the inclination of the said slots causes the slide to rise and raise the pawls from the teeth of the feed-rack, and when the slide is moved backward the inclination of the said slots compels it to move downward and lower the pawls into engagement with said feed-rack. In order that the said slide may be raised when the pole-carriage reaches the end of its forward stop O is secured to the rear end of the feedrack K in a position to come in contact with said slide N and compel it io move endwise and rise, and a spring-pawl n, Figs. 3 and 13, is provided to engage with the head n2 of one of the pins and hold the slide in its raised position with a yielding pressure. In order that the said slide may be moved backward when the carriage reaches the end of its retrograde movement,a second stop O is secured to the forward end of the rack-bar -K in position to come in contact with the slide N and move it backward and downward as IOO IIO

movement, a

the carriage reaches the end of its retrograde movement, the spring-pawl n' yielding to the pressure produced by the action of the stop O.

In order to insure the lifting of bothpawls clear of the rack-bar, it is expedient to make the last tooth 768 of the rack-bar a little higher than the others, so that when the slide has been raised high enough to disengage the feed-pawl K,-from this lasttooth the stoppawl has been lifted entirely clear of the teethof the rack-bar in advance of it. WVhen the. carriage reaches the end of its forward movement, the drivin g-belt should be shifted from the fast pulley I to the loose pulley I', so as to stop the operation of the shiftingrods while the carriage is being retrograded. This shifting of the belt may be done by hand; but inthe apparatus represented inthe drawings a belt-shipperis provided, which maybe operated either by hand or by the movement of the carriage. The bar P of this belt-shipper is fitted to slide in brackets connected with the frame of the machine, and for the purpose of enabling it to be operated by hand the bar of the shipper is connected by a link p and an elbow-lever p2 with a hand shipper-rod P', which extends, preferably, along the main frame lengthwise thereof and is supported in one or more guides p, so that itv is within reach of the attendant standing at one side of the apparatus and can be readily operated by him. In ord er that the said beltshipper may be operated when the carriage reaches the end of its forward movement, the

belt-shipper is combined with the carriage.

To this end the bar P of the shipper is connected by an elbow-lever p4 with the ship` per-rod P2, which extends lengthwise of the frame of the machine and is supported thereon in one or more guides, and this shipperrod P2 is provided with two stops 195176, Fig. l, which are moved alternately by means of the shipping-arm p7, secured to the pole-carriage D. Hence when the pole-carriage approaches the end of its forward movement the shipping-arm p7, acting upon the stop p5, moves the shipper-rod P2 and the shipper P with which that rod is connected, so as to shift the belt from the fast to the loose pulley, I

thus causing the cam-shaft H and the reciprocating shifting-rods E, which are operated bymeans of the cams on that cam-shaft, to Stop, and as the carriage approaches the end of its retrograde movement the shipping-arm ments of the carriage. The indicator which we prefer to use has the form of a ratchettoothed disk R, which is moved the space of one tooth for each forward movement of the pole-carriage. For this purpose an elbow-lever R is supported upon the frame of the machine with its lower arm in position to be struck by the end of the pole-carriage D (or by a projection from it) as the carriage Vapproaches the end of its retrograde movement, and a springris provided to move the elbowlever R in the reverse direction as the polecarriage is moved forward. The distance to which the elbow-lever can be moved by the spring o" is limited by a pin r', and the elbowlever is fitted with a hook r3, which engages with the ratchet-teeth of the indicator with a yielding pressure incident to the action of a spring r2. The retrograde movement of the pole-carriage causes the hook r3 to rise and take hold of the next succeeding tooth of the indicator, while the forward movement of the pole-carriage permits the hook-spring r to draw the hook downward, and thus turn the indicator the space of a tooth.

In order that the indicator may be prevented from retrograding while its hook r3 is being moved to engage with ay succeeding tooth, the indicator is provided with a friction-band, (shown in dotted lines at Fig. 2,) which grasps the stud on which the indicator R turns. An index r4 also is provided to show the number of teeth of the indicator which have been moved past it, therebyindieating the number of operations of the polecarriage.

When the pole-carriage has been moved to and fro the desired number of times, the operation o-f the apparatus may be stopped by turning the feed-pawl K by hand upward and backward, so as throw it out of engagement with the feed-rack K; but we prefer that the stoppage should be effected by the operation of the apparatus itself when the polecarriage has completed its last forward movement. For this purpose the mechanism represented in Fig. 13 may be employed, a pinwheel S, having at least as many pin-holes s as the number of forward movements of the pole-carriage which are to be effected before the apparatus is stopped, being pivoted to the frame of the apparatus. The pin-wheel is litted with a movable pin s, and the slide N is provided with a pivoted hook S', which is held within the range of movement of the said pin s of the pin-wheel by means of a guide s2.

In order that the pin-wheel may be moved, its rim is preferably formed into ratchetteeth, and a reciprocating hook s3 is provided ofthe spring 37.

lwith the swinging hook S riage approaches the end of its forward movement the hook s3 is moved forward to engage with the next succeeding tooth of the pinwheel S. to retrograde, its depending leaves the hook-arm S4, which is then pulled backward by the operation of a spring $7, so as to turn the pin-wheel the angular distance between two succeeding pin-holes. A stop S8 is provided to limit the distance to which the hook s3 can be moved by the operation The movable pin s is placed in the proper hole of the pin-wheel S to be turned to the position in which it is represented in Fig. 13 during the forward movement next preceding the last-desired forward movement of the pole-carriage, so that when the feed-pawl K moves forward in engagement with the last tooth 7t8 of the feed-rack K the pole-carriage being moved thereby has its depending projection s brought in Contact with the projection of the hook-arm s4, and the hook is thereby moved forward to the next succeeding ratchet-tooth of the pinwheel. lVhen, then, the pole-carriage begins to move backward under the operation of the weight K4, the hook-spring s, moving the pin-wheel, and the movable pin s, carried by the pin-wheel, cause the lat-ter to engage and pull the slide N rearward sufficiently to drop the pawls K 756 into engagement with the rack-bar K and stop its further backward movement with the carriage by the operation of the weight K4. As the belt-shipper has been moved during the last forward movement of the carriage to shift the driving-belt to the loose pulley, the revolution of the cam-shaft H has been stopped previous to the commencement of projection .s-G

the retrograde movement of the pole-carriage,

so that when the slide N has" been operated by the pin of the pin-wheel, as above described, and -the retrograde movement has been checked by the dropping of the pawls into engagement with the rack -bar K all parts of the apparatus remain at rest until again started by the operator by shifting the movable pin s to another hole (or by turning the pin-wheel S backward the number of holes corresponding with the number of operations of the carriage to be made in dyeing the next lot of hanks) and by moving the slide N forward, thereby lifting the pawls, so as to permit the carriage to be retrograded by the weight K4. Vhen the hanks of yarn have been sufficiently dyed, they may be removed from the apparatus by lifting each pole separately and carrying it` away from the dye-vat; but as this separate removal of the poles would occupy considerable time we prefer to raise the pole-frame D, with all its poles "and with the hanks hanging upon said poles, bodily from the dye-vat. In order that this maybe effected readily, we prefer to fit the pole-frame D with eyes c', with which hooks connected with lifting-chains maybe engaged, so that the said chains and the polel/Vhen the pole-carriage commences frame with which they are connected maybe raised by power and the pole-frame may be transferred from the apparatus, and that another pole-frame, to the poles of which a new set of hanks have been applied, may be transferred to the pole-carriage.

The operation of our said apparatus is as follows: Assuming that a pole-frame D', supplied with hanks of varn hanging from its poles, has been applied to the apparatus, the pole-carriage is permitted to be retrograded until the most forward pole of the series is opposite the ends of the endwise-reciprocating` shifting-rods E. As the driving-belt is shifted to the fast pulley I by the time the retrograde movement of the carriage stops, the shifting-rods E immediately commence to operate by the action of the shifting-cam E and enter endwise into the cavity of the first pole and into the bights of yarn hanging thereon. lVhen the shifting-rods have been entered their full distance, they are raised by the lifting-cam F2 and lift the hanks of yarn. During this lifting movement the feed mechanism moves the carriage forward half the distance between two successive poles, the first projection or grade t of the feed-cam K2 operating for this purpose. When, then, the shifting-rods are lowered by the action of the lifting-cam F2, they lower the hanks of yarn into the dye-vat in the space between the lifting-rods and the pole from which the hanks were lifted, the hanks then hanging in the form of loops. W'hen the shifting-rods have been lowered, they are withdrawn from the bights of the hanks, and as they are withdrawn the stripper .l for each endwise-reciprocating shifting-rod prevents the bights of the hanks from moving outward of the dyevat with the shifting-rod. As the shiftingrods are withdrawn endwise from the bights of the banks with which they are engaged the hanks drop into the dye-vat. When the endwise-reciprocatingshifting-rodshave been withdrawn, the second projection 15 of the feed-cam K2 comes into operation and operates the feed-pawl K to move the pole-carriage the distance of one tooth of the feed-bar, thus bringingthe second pole of the series opposite the ends of the shifting-rods, so that thehanks of yarn hanging on the second pole may be shifted in turn. The operation of shifting the hanks hanging upon each pole is repeated until the pole-carriage reaches its most forward position and the yarn upon all the poles has been shifted, whereupon the pawls K k6 are thrown out of engagement, as previously described, (by the operation of the slide N,) and the carriage is retrograded by the weight K1 to have the shifting of the hanks of yarn repeated. lVhen the movements of the carriage have been repeated the required number of times, the operation of the machine is stopped, thev dyed hanks ofl yarn are removed from the dye-vat, and fresh hanks are put in their places. During the retrograde movement of the carriage the IOO IIO

trailing of the hanks of yarn in the dyeliquor operates as a brake to slow down the movement of the carriage by the action of the Weight K4, and the amount of this weight should be adjusted in accordance with the number of hanks which are to be dyed at any one time, so that the carriage may not retrograde too rapidly. As the number of hanks dyed at any one operation may vary, We prefer to construct the Weightin sections, as represented at Fig. 2, more or less of Which sections may be used as found expedient for the number of the hanks of yarn. The presence of the hand shipper-rod P at the side of the apparatus enables the attendant to stop the operation of the apparatus at any-time in case such stoppage be expedient.

Itis possible that the endWise-reciprocating shifting-rods when lowered between the poles may from some accident be not withd rawn to their full extent, in which event the next feeding movement would bring the next succeeding pole against the shifting-rod and bend it. ln order to provide against risk of injury from such a contingency and to give the attendant time to notice such difficulty, the lifting-cam F2 is fitted With a second but low lifting-grade n', Fig. l1, which makes a second but slight lift and lowering of the shifting-rods E after they have been lowered by the main grade o, and raises them free of the edges of the next succeeding pole, and thus prevents injury in case the end of the shifting-rod has not been sufficiently withdrawn to clear the pole.

Vire prefer to apply a counterpoise X, Fig. l, to counterbalance the Weight of the banks of yarn and to connect this counterpoise with the rock-shaft G by means of an arm X.

Although the above-described apparatus embodies all parts of our invention in the forms in which We prefer to construct them, it is evident that more or less of those parts may be used as found expedient. Thus, for example, the combination of the belt-shipping device with the pole-carriage may be broken by removing the stops p5 and p, so

` that the apparatus is not stopped by its own operation when the carriage is t-o be retrograded Without affecting the combination of the pole-carriage with the endwise-reciproeating shifting rod or rods. So, also, one end- Wise-reciprocating shifting-rod may be removed, leaving one only to be operated. The main frame also may be constructed complete for use with. more or less of the operating members, and may be sold Without the dye-vat,leaving the purchaser to add the dyevat in his dyehouse.
